Parameters

db
Type: GeoEngine.Core.GXNetCDB
[i] database handle
lst
Type: GeoEngine.Core.GXNetCLST
[i] channels of data to get
m_ch
Type: SystemInt32
[i] mask channel (can be <define>NULLSYMB</define>)
vv_trans
Type: GeoEngine.Core.GXNetCVV
[i] transforms to apply
remove_dummy_rows
Type: SystemInt32
[i] remove dummy rows?
vv_dummy
Type: GeoEngine.Core.GXNetCVV
[i] dummy row if this channel value is dummy (0:No, 1:Yes)? Effective only if "remove dummy rows" value is TRUE
warn
Type: SystemInt32
[i] warn if rows removed because of dummy data items?
vv_d
Type: GeoEngine.Core.GXNetCVV
[o] (INT) returned data - one VV handle per channel
vv_line
Type: GeoEngine.Core.GXNetCVV
[o] line symbols selected
vv_n
Type: GeoEngine.Core.GXNetCVV
[o] number of original data items in each line
vv_used
Type: GeoEngine.Core.GXNetCVV
[o] number of non-dummy rows
vv_index
Type: GeoEngine.Core.GXNetCVV
[o] indices into original data
vv_fids
Type: GeoEngine.Core.GXNetCVV
[o] Fid Starts (REAL)
vv_fidi
Type: GeoEngine.Core.GXNetCVV
[o] Fid Increments (REAL)
Remarks
This function is a quick way to get all rows of data, guaranteeing no dummy items. Book-keeping VVs returned let you easily write back results to new channels in the correct locations. Set the "Dummy Row" VV to 1 if you wish to remove any row where a value for the corresponding channel is a dummy. Transforms to apply: -1 - Channel default (will be either raw or log) 0 - Raw Transform 1 - Log transform: base e with log min = CHIMERA_LOG_MIN 2 - Lambda transform
